A lot of times, when it comes to memory, people always ask is PC2400/PC2700/PC3000 really that much faster then PC2100? and my usual reply is If you're into overclocking, then yes the higher rated RAM allows you to run your FSB higher should your other system components allow it. Many times the person's rebuttal is, Oh, I don't plan to overclock though. While I love getting e-mails from our readers, I sometimes don't have time to answer all of the questions I receive. Hopefully this article should answer many of the questions a lot of people have when faced with buying new memory for their computer.
